Fatented Apr. 2 7, 1937 UNITED STATES PATENT OFFICE 2,078,400 5 INSULATED SANITARY :COVER FOR MILK Y CANS Kenneth A. Maupin, Eaton Rapids, Mich.- Application une 27, 1936, Serial No. 87.810- 8 claims. (oi. 150-423 This invention relates to insulating sanitary 'covers for milk cans and the like. Heretoforein transporting milk cans it has been necessary to buckle on cumbersome stiff covers of hair felt or the like with handles thereon for handling the cans. Such covers are of excessive weight due to the necessity for the buckles and straps and are unsatisfactory in that they must be stiff and formed in order to properly contain the can which makes the storage of these covers quite a problem.

The objects of this invention are:

First, to provide an effectively closed insulated can cover which protects and insulates a milk can and which does not interfere with the handling of the can during hauling or shipment.

Second, to provide such a structure which is provided with effective provision for handling the can while keeping it sealed and protected from dirt and infiltration of heat.

Third, to provide such a can cover with an improved insulating material whereby the weight of the article is materially reduced. I

Fourth, to provide an improvement in the insulating material itself.

Fifth, to provide such a can cover which may be compactly folded and stacked and stored with the greatest of ease.

Sixth, to provide such a can cover which may be conveniently placed on the can and removed and will allow the loading of more cans in a given floor space.

Seventh, to provide such a can cover which effectively keeps out all dirt and insects and which may be turned inside out for airing and washing.

Eighth, to provide such an insulating cover which may be made very inexpensively and is more efiicient than the can covers heretofore employed.

I accomplish the objects of my invention by the structure described in the following specification and illustrated in the accompanying drawing, in which 2 Fig.1 is a perspective view of a milk can with my improved insulating structure in position thereon, the milk can being entirely covered and concealed thereby.

Fig. 2 is an enlarged detail elevation partly in section through the can and its handles, showing the details of construction andhow the can may be handled with my insulating cover thereon.

Fig. 3 is a detail sectional View through the insulating cover showing the construction thereof.

Fig. 4 isa view of my cover off the can and folded inv position for storage.

In the drawing, I is the usual metallic milk can with the reduced neck at the top and the usual handle 2 thereon. 3 is my improved insulati'n'g' cover. It'is an open bottom bag closed at the top having double walls 4 and 5 preferably'made of waterproofed canvas. The bag is of'a size to fit snugly oyer the head of a milk can and in the sides of the bag opposite the location of the handles of a can enclosed therein I provide extra'fullness forming a pair of closed pockets 6 which can be tucked over and around the handles. ofa milk can as shown in Fig. 2, so

that the handle may be grasped with my cover inlpla'ce'as shown in Fig. ,2, lhe hands of a person handling the can are shown at I. With this arrangement I make possible the grasping of the can by the handles 2 already provided thereon without any openings through whigh dirt or' insects may pass or through which heat infiltrationmay take place. 7

Between the double'walls of my protector, 'provide insulating material '8. In the center of the insulating material I provide a sheet 9 of cellophane or regenerated cellulose which is impervious to the air. The sheet shown is reinforced by thread I0 woven in'the form of a mesh and with this sheet it is possible to preventin filtration of the air even though the outer fabric 4 or the inner fabric 5 of the protector may become torn. The insulating material 8 which I employ is a wool bat which I produce in a woolen mill especially for this purpose. The wool is thoroughly cleansed to make it lively and resilient. I cross the fibers in the arrangement so that it will be permanently retained in position between the outer wall 4 and the inner wall 5 of the structure. I prefer to retain thisbat in place by suitable quilting stitching l l although it will be appreciated that when I refer to quilting I am referring to stapling or other suitable means for holding the padding in place between the double walls. v

The structure I have produced is'like an inverted sack, adapted to seal around the can on the floor or platform at the bottom. I put an annular row of quilting stitches l2 near the bottom, forming a special annular filled section I3 at the bottom, which contacts with the floor and spreads out and makes practically an air-tight and vermin-tight joint at that point; also the protector fits the can closely and is entirely closed and stitched closed at the top. It is thus proof against insects or contamination. At points to the front and rear of the can I quilt-stitch a central pad M which serves to retain the outer wall and the lining in proper relation to this filling material.

5 The air is confined within by this double wall and the insulation is thus maintained. Air is also confined about the top to the container in the space l5. It will be apparent that my structure eliminates a change of air about the can and over the milk, thus eliminating the possibility of bacterial contamination from outside.

At the top I stitch in a loop "5 which serves as the handle for the structure. The structure can be turned inside out for cleansing, sterilizing or repair. I have shown the structure as applied to a milk can. It will protect any similar can. I do not show a bottom. One could be provided. The protector is very efficient without it and is used in that form.

I desire to claim the invention in its specific form and also broadly as in the appended claims.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

l. A protector for a milk can or the like having handles, comprising an open-bottom closed-top bag formed of double walled fabric, said bag being of a size to fit snugly over the body of a milk can or the like and having at the sides thereof opposite the location of the handles of a can enclosed therein an extra fullness forming a pair of closed pockets to be tucked under and about the handles of a milk can whereby the can is protected and the handles may be grasped by the hands, and insulating material, and a sheet of air impervious material enclosed between the double walls of said bag in the portions of the bag .other than said pockets, and a row of quilting stitches in proximity to the bottom of said bag to form a tubular part adapted to contact with the floor around the bottom of the can to form a seal.

2. A protector for a milk can or the like having handles, comprising an open-bottom closed-top bag formed of double walled fabric, said bag being of a size to fit snugly over the body of a milk can or the like and having at the sides thereof opposite the location of the handles of a can enclosed therein an extra fullness forming a pair of closed pockets to be tucked under and about the handles of a milk can, whereby the can is protected and the handles may be grasped by the hands, and insulating material enclosed between the double walls of said bag in the portions of the bag other than said pockets, and a row of quilt- 5 ing stitches in proximity to the bottom of said bag to form a tubular part adapted to contact with the floor around the bottom of the can to form a seal.
